Help with Calling a Double Array in C++ Function

You might want to clarify the exact error message you’re getting, since it sounds like there are two separate issues. One could be with your function definitions and calls. Remember that for arrays, you should be using the `[]` syntax in your function prototype (like `double totalfall(double rainfall[], int size)`). Also, make sure you’re consistent with using `double` types. Regarding values not carrying over, make sure you're not accidentally shadowing your variable names inside the main function. If that’s the case, your functions would be working with copies instead of the actual data.

Don’t forget to check your loops and input handling! In your for loop, it looks like you should add a separate check to ensure that the input is valid. If the input is negative, you're relying on a while loop that might cause problems in your program flow. Make sure all array accesses stay within bounds and double-check the array indices. If you’re using an IDE, run the debugger; it can help spot where things are going wrong.

It sounds like you might have some confusion about how to pass arrays to functions in C++. When you declared your `totalfall` function, you're passing a single double instead of an array. Change the parameter to accept a double array like this: `double totalfall(double arrayRain[], int size)`. This way, you're properly passing the whole array. Also, when you're trying to access array values, make sure you've passed the right size and data type. If you're still getting that 'cannot convert' error, check if you're adding any pointers incorrectly. Let me know if this helps!
